Yup, colossal loss when you consider that 3 lives were ended abruptly, and also a sad demise for a very special car.
LM, are you aware of which chassis was the one that was backed into an Armco barrier and written off? A while ago someone (was it you, I don't remember?) was selling a wall placque from McLaren that had the chassis numbers and histories listed--if it was you, and you still it or a copy of it, would you mind looking this up?
